DETAILED DESCRIPTION

The description that follows discusses illustrative examples of thedisclosure. In the following description, for the purposes ofexplanation, numerous specific details are set forth in order to providean understanding of various examples of the disclosed subject matter. Itwill be evident, however, to those skilled in the art, that examples ofthe disclosed subject matter may be practiced without these specificdetails. In general, well-known instruction instances, protocols,structures, and techniques are not necessarily shown in detail.

Typical systems allow users to create personal videos by using afront-facing camera of a mobile device. By using the front-facing camerathe user can see themselves on the screen of the phone while recording avideo. This ensures that the user is capturing a video of what the userintends. To do so, for example, a typical mobile phone includes afront-facing camera and the user can interact with the touchscreen ofthe mobile phone to select between various options to capture a video ofthe user. Namely, the user can select an option on the touchscreen bymaking physical contact with the screen to start capturing a video clipof the user with the front-facing camera. After the user selects theoption, the user has to position the mobile phone in a way that capturesa full body of the user and then the user has to back away from themobile phone. Because of this setup process involved in using thefront-facing camera to create video clips, a tremendous amount of effortis required to remove and edit unwanted segments of the video clips(e.g., showing the user backing away from the mobile phone and thencoming up to the phone to stop recording). Also, because the setupprocess requires the user to physically interact with the mobile phoneto control the front-facing camera and capture video clips, a user mayneed to perform multiple takes and record the video clip multiple timesto make various corrections to the positioning and placement of the userin the video.

The disclosed examples improve the efficiency of using the electronicdevice by automatically activating a hands-free mode of operation thatenables a user to remotely control an electronic mirroring device, suchas a front-facing video camera of a mobile phone, using a finger (ordigit) of a hand or other body part as a cursor. In one example, thehands-free mode of operation is activated when one or more conditionsare satisfied. For example, the disclosed examples can capture, by anelectronic mirroring device, a video feed received from a camera of theelectronic mirroring device that depicts a user. The electronicmirroring device evaluates a set of conditions for activating ahands-free mode of operating the electronic mirroring device and, inresponse to determining that the set of conditions are satisfied, thehands-free mode of operating the electronic mirroring device isactivated. The electronic mirroring device performs one or morefunctions on the electronic mirroring device based on detection of oneor more gestures performed by the user in the video feed. Specifically,the electronic mirroring device allows a user to navigate throughdifferent whole-body outfits, capture one or more video clips,communicate with friends of the user, apply one or more filters oractivate one or more augmented reality experiences remotely using thehands-free mode of operation.

This allows the user to remotely control the electronic mirroring devicewhich simplifies capture of video clips by the front-facing camera ofthe electronic mirroring device without having to physically touch orinteract with the electronic mirroring device. For example, theelectronic mirroring device can be fixed on a camera stand so that thefront-facing camera is pointing towards a target or object to becaptured. After fixing the electronic mirroring device on the camerastand the user can back away from the electronic mirroring device. Theelectronic mirroring device can detect a whole-body of the user in thefield of view of the camera and, in response, activate a hands-free modeof operation. In response, the user can control options that aredisplayed on the electronic mirroring device by pointing to thoseoptions (e.g., in a way that is natural to the user) to select theoptions or using specific hand gestures to navigate through and selectbetween different options. This reduces the amount of resources neededto operate a given device and improves the overall efficiency ofelectronic devices. This increases the efficiency, appeal, and utilityof electronic devices.

In some cases, the electronic mirroring device includes a combination ofan electronic eyewear device facing a static non-electronic orelectronic mirror. The user can wear the electronic eyewear device toview the static mirror through lenses of the electronic eyewear deviceto see themselves. In this case, the electronic mirroring deviceincludes a camera that points towards the static mirror and captures avideo of the user in the mirror. The electronic eyewear device displaysone or more menu options (for controlling whole-body outfits displayedby the electronic eyewear device) in the lenses of the electroniceyewear device at a position in relation to the user in the mirror. Thismakes it appear to the user as if the menu options are being displayedon the mirror above, below or next to the user. The hands-free mode ofoperations is automatically activated in response to the camera of theeyewear device detecting a whole body of the user being depicted in thereflection of the user in the static mirror. In this case, the user canuse hand or finger gestures and movements to select between the one ormore menu options to control options displayed on the electronic eyeweardevice that appear to be displayed over a reflection of the user in themirror in an image or video captured by the camera of the electroniceyewear device.

Networked Computing Environment

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network.The messaging system 100 includes multiple instances of a client device102, each of which hosts a number of applications, including a messagingclient 104 and other external applications 109 (e.g., third-partyapplications). Each messaging client 104 is communicatively coupled toother instances of the messaging client 104 (e.g., hosted on respectiveother client devices 102), a messaging server system 108 and externalapp(s) servers 110 via a network 112 (e.g., the Internet). A messagingclient 104 can also communicate with locally-hosted third-partyapplications 109 using Applications Program Interfaces (APIs). Themessaging system 100 includes an eyewear device 119, which hosts ahands-free control system 107, among other applications. The eyeweardevice 119 is communicatively coupled to the client device 102 via thenetwork 112 (which may include via a dedicated short-range communicationpath, such as a Bluetooth™ or WiFi direct connection). The messagingsystem 100 includes an electronic mirroring device 130, which may hostanother instance of the hands-free control system 107, among otherapplications. The electronic mirroring device 130 can include similarfunctionality as the client devices 102.

The hands-free control system 107 can activate and control a hands-freemode of operation that allows a user to navigate through and selectbetween various menu options that are displayed on a screen of theeyewear device 119 or the electronic mirroring device 130 by pointingthe user's finger towards the direction of the desired menu option ormoving the user's hand towards a given option. For example, thehands-free control system 107 can receive or capture a video feed from acamera of the eyewear device 119 or the electronic mirroring device 130.Specifically, the hands-free control system 107 can receive or capture avideo feed from a front-facing camera of the electronic mirroring device130, such as the front-facing camera of a mobile phone. In anotherimplementation, the hands-free control system 107 can receive or capturea video feed from a camera of the eyewear device 119 that is pointingtowards a static mirror. The static mirror reflects an image of the userwhich is captured as a video feed by the camera of the eyewear device119.

The hands-free control system 107, in response to or based on the videofeed, evaluates a set of conditions for activating a hands-free mode ofoperating the electronic mirroring device 130. The set of conditions caninclude a detection that an on-screen option has been selected forperforming one or more functions, such as applying a filter or augmentedreality elements to an image or video or activating recording operationof a camera. The set of conditions can include a determination based onanalysis of or performance of object recognition in the video feed ofwhether a whole body of the user is depicted in the video feed. Thisdetermination can be performed in response to receiving the selection ofthe on-screen option. As referred to herein, a “whole body” of the userincludes a predetermined combination of one or more skeletal body partsor joints of the user e.g., a combination of a head joint, shoulderjoints, and arm joints; a combination of shoulder joints and a hipjoint; or a combination of a head joint, shoulder joints, hip joints,and leg joints). The hands-free control system 107 can perform objectrecognition on the captured video feed to detect presence of one or moreskeletal joints of a user. In response to determining that the detectedskeletal joints match a predetermined combination, the hands-freecontrol system 107 determines that the whole body of the user isdepicted in the video feed.

As another example, the set of conditions can include the receipt ofinput that selects an augmented reality experience from a plurality ofaugmented reality experiences. Augmented reality experiences can includethe display and inclusion of one or more augmented reality elements onan image or video that is captured by the camera of the electronicmirroring device 130. Each augmented reality experience of the pluralityof augmented reality experiences can be a different lens or filter andcan control display and animation of a difference set of augmentedreality elements. The set of conditions can include a determination ofwhether the selected augmented reality experience is associated withhands-free operations. In response to determining that the selectedaugmented reality experience is associated with the hands-freeoperations, the hands-free control system 107 can automatically activatethe hands-free mode of operating the electronic mirroring device 130.

In some examples, the set of conditions can include a condition that thecamera is a front-facing camera and that the front-facing camera isstationary. For example, the hands-free control system 107 can determinethat the front-facing camera has been activated and is capturing a videofeed. The hands-free control system 107 determines that the amount ofphysical movement of the electronic mirroring device 130 is less than athreshold over a given time interval (e.g., 2 seconds). To do so, thehands-free control system 107 can access a gyroscopic component of theelectronic mirroring device 130 and determine that measurements outputby the gyroscopic component indicative of movement do not vary by morethan a specified threshold (e.g., the electronic mirroring device 130moves less than 2 millimeters over a two second duration). In responseto determining that such set of conditions are satisfied, the hands-freecontrol system 107 can then begin the process for evaluating additionalsets of conditions, such as to determine whether a whole body of theuser is depicted in the video feed.

After and in response to activating the hands-free mode of operating theelectronic mirroring device 130 when the set of conditions aresatisfied, the hands-free control system 107 can modify or increase adisplay attribute of a display of the electronic mirroring device 130.For example, the hands-free control system 107 can increase a brightnessof the display, increase a size of one or more graphical elements thatare displayed on the display, such as one or more menu options, oractivate a light (e.g., an LED) that is provided around a border of theelectronic mirroring device 130, or combination thereof. The hands-freecontrol system 107 can then display one or more menu options on thedisplay of the electronic mirroring device 130 or within lenses of theeyewear device 119. The hands-free control system 107 detects one ormore fingers of a hand (or other body part) of the user in the videofeed, such as using an object recognition process. Once the one or morefingers of the hand of the user are detected, the hands-free controlsystem 107 determines the direction to which the one or more fingers arepointing. For example, the hands-free control system 107 draws orgenerates a virtual line that extends or runs along the one or morefingers parallel to the one or more fingers. The hands-free controlsystem 107 determines whether a display position of at least a portionof a given menu option of the one or more menu options is intersected bythe virtual line. In response to determining that the virtual lineintersects the display position of at least the portion of the givenmenu option, the hands-free control system 107 activates, accesses orgenerates an indication relating to the given menu option. As anotherexample, the hands-free control system 107 determines a position withinthe screen of the hand of the user. The hands-free control system 107can determine that the on-screen position of the hand in the video feedoverlaps a display position of a given option of the one or more menuoptions. In response, the hands-free control system 107 activates orperforms a function associated with the option when the hand continuesto overlap the display position of the given option for a thresholdperiod of time (e.g., 2 seconds).

In some implementations, the hands-free control system 107 cancommunicate with an on-board camera of the eyewear device 119 todetermine or detect presence of the one or more fingers of a user's handwithin view of the lenses of the eyewear device 119. For example, thecamera may continuously or periodically scan real-world objects that areincluded in one or more images or a real-time video feed of the camera.The hands-free control system 107 may determine whether the real-worldobjects correspond to fingers of a human hand. In response todetermining that the real-world objects correspond to a human hand, thehands-free control system 107 may determine that a user's hand has beendetected within view of the lenses of the eyewear device 119. Forexample, the camera of the eyewear device 119 can point towards a staticmirror and can display the one or more menu options within lenses of theeyewear device 119 positioned within the static mirror. The staticmirror can reflect an image of the user wearing the eyewear device 119.The camera of the eyewear device 119 can capture the reflection from thestatic mirror and process the reflection to detect the one or morefingers of the hand of the user. The hands-free control system 107 canthen determine and track the position of the one or more fingers of thehand of the user and determine the direction to which the one or morefingers are pointing. In such cases, the hands-free control system 107activates menu options when the direction of the one or more fingers ofthe hand position are pointing to the positions of different ones of themenu options.

In some implementations, the electronic mirroring device 130 can befixed on a camera stand so that the front-facing camera is pointingtowards a target or object to be captured. The hands-free control system107 can be integrated and run on the electronic mirroring device 130.After fixing the electronic mirroring device 130 on the camera stand,the user can back away and control options that are displayed on theelectronic mirroring device 130 by making various hand or fingermovements. The hands-free control system 107 can track the movement ofthe hand and/or fingers of the hands in the images captured by thefront-facing camera and navigate to and select various displayedoptions.

The hands-free control system 107 can allow the user to perform variousfunctions remotely during the hands-free mode of operation. For example,the hands-free control system 107 can allow the user to capture a videoclip of the user of a specified duration, such as a 5 second video clip.Namely, after automatically activating the hands-free mode of operation(e.g., fixing the camera of the electronic mirroring device 130 on asurface, selecting an on-screen video clip generation option, anddetecting a whole body of the user in the video feed captured by thecamera), the hands-free control system 107 can present one or moreoptions for controlling the capture of the video clip. In one example,the hands-free control system 107 automatically displays a countdowntimer that automatically begins capturing the video clip after the wholebody of the user is detected in the camera feed for a threshold periodof time (e.g., 5 seconds). In another example, the hands-free controlsystem 107 can determine that the user's hand is positioned over a begincapture option in the camera feed. In response, the hands-free controlsystem 107 automatically begins capturing the video clip after the wholebody of the user is detected in the camera feed for a threshold periodof time (e.g., 5 seconds). In one example, the hands-free control system107 can change a filter being applied to the video clip or a duration ofthe video clip in response to determining that the user's hand ispositioned over a respective option for changing the filter or duration(or if the user's finger is determined to point towards the respectivefilter or duration setting option).

A messaging client 104 is able to communicate and exchange data withother messaging clients 104, the eyewear device 1119, and with themessaging server system 108 via the network 112. The data exchangedbetween messaging clients 104, and between a messaging client 104 andthe messaging server system 108, includes functions (e.g., commands toinvoke functions) as well as payload data (e.g., text, audio, video orother multimedia data).

The messaging server system 108 provides server-side functionality viathe network 112 to a particular messaging client 104. While certainfunctions of the messaging system 100 are described herein as beingperformed by either a messaging client 104 or by the messaging serversystem 108, the location of certain functionality either within themessaging client 104 or the messaging server system 108 may be a designchoice. For example, it may be technically preferable to initiallydeploy certain technology and functionality within the messaging serversystem 108 but to later migrate this technology and functionality to themessaging client 104 where a client device 102 has sufficient processingcapacity.

The messaging server system 108 supports various services and operationsthat are provided to the messaging client 104. Such operations includetransmitting data to, receiving data from, and processing data generatedby the messaging client 104. This data may include message content,client device information, geolocation information, media augmentationand overlays, message content persistence conditions, social networkinformation, and live event information, as examples. Data exchangeswithin the messaging system 100 are invoked and controlled throughfunctions available via user interfaces (UIs) of the messaging client104.

Turning now specifically to the messaging server system 108, anApplication Program Interface (API) server 116 is coupled to, andprovides a programmatic interface to, application servers 114. Theapplication servers 114 are communicatively coupled to a database server120, which facilitates access to a database 126 that stores dataassociated with messages processed by the application servers 114.Similarly, a web server 128 is coupled to the application servers 114,and provides web-based interfaces to the application servers 114. Tothis end, the web server 128 processes incoming network requests overthe Hypertext Transfer Protocol (HTTP) and several other relatedprotocols.

The Application Program Interface (API) server 116 receives andtransmits message data (e.g., commands and message payloads) between theclient device 102 and the application servers 114. Specifically, theApplication Program Interface (API) server 116 provides a set ofinterfaces (e.g., routines and protocols) that can be called or queriedby the messaging client 104 in order to invoke functionality of theapplication servers 114. The Application Program Interface (API) server116 exposes various functions supported by the application servers 114,including account registration, login functionality, the sending ofmessages, via the application servers 114, from a particular messagingclient 104 to another messaging client 104, the sending of media files(e.g., images or video) from a messaging client 104 to a messagingserver 118, and for possible access by another messaging client 104, thesettings of a collection of media data (e.g., story), the retrieval of alist of friends of a user of a client device 102, the retrieval of suchcollections, the retrieval of messages and content, the addition anddeletion of entities (e.g., friends) to an entity graph (e.g., a socialgraph), the location of friends within a social graph, and opening anapplication event (e.g., relating to the messaging client 104).

The application servers 114 host a number of server applications andsubsystems, including for example a messaging server 118, an imageprocessing server 122, and a social network server 124. The messagingserver 118 implements a number of message processing technologies andfunctions, particularly related to the aggregation and other processingof content (e.g., textual and multimedia content) included in messagesreceived from multiple instances of the messaging client 104. As will bedescribed in further detail, the text and media content from multiplesources may be aggregated into collections of content (e.g., calledstories or galleries). These collections are then made available to themessaging client 104. Other processor- and memory-intensive processingof data may also be performed server-side by the messaging server 118,in view of the hardware requirements for such processing.

The application servers 114 also include an image processing server 122that is dedicated to performing various image processing operations,typically with respect to images or video within the payload of amessage sent from or received at the messaging server 118.

Image processing server 122 is used to implement scan functionality ofthe augmentation system 208. Scan functionality includes activating andproviding one or more augmented reality experiences on a client device102 when an image is captured by the client device 102. Specifically,the messaging client 104 on the client device 102 can be used toactivate a camera. The camera displays one or more real-time images or avideo to a user along with one or more icons or identifiers of one ormore augmented reality experiences. The user can select a given one ofthe identifiers to launch the corresponding augmented realityexperience. Launching the augmented reality experience includesobtaining one or more augmented reality items associated with theaugmented reality experience and overlaying the augmented reality itemson top of the images or video being presented.

The social network server 124 supports various social networkingfunctions and services and makes these functions and services availableto the messaging server 118. To this end, the social network server 124maintains and accesses an entity graph 308 (as shown in FIG. 3) withinthe database 126. Examples of functions and services supported by thesocial network server 124 include the identification of other users ofthe messaging system 100 with which a particular user has relationshipsor is “following,” and also the identification of other entities andinterests of a particular user.

Returning to the messaging client 104, features and functions of anexternal resource (e.g., a third-party application 109 or applet) aremade available to a user via an interface of the messaging client 104.The messaging client 104 receives a user selection of an option tolaunch or access features of an external resource (e.g., a third-partyresource), such as external apps 109. The external resource may be athird-party application (external apps 109) installed on the clientdevice 102 (e.g., a “native app”), or a small-scale version of thethird-party application (e.g., an “applet”) that is hosted on the clientdevice 102 or remote of the client device 102 (e.g., on third-partyservers 110). The small-scale version of the third-party applicationincludes a subset of features and functions of the third-partyapplication (e.g., the full-scale, native version of the third-partystandalone application) and is implemented using a markup-languagedocument. In one example, the small-scale version of the third-partyapplication (e.g., an “applet”) is a web-based, markup-language versionof the third-party application and is embedded in the messaging client104. In addition to using markup-language documents (e.g., a .*ml file),an applet may incorporate a scripting language (e.g., a .*js file or ason file) and a style sheet (e.g., a .*ss file).

In response to receiving a user selection of the option to launch oraccess features of the external resource (external app 109), themessaging client 104 determines whether the selected external resourceis a web-based external resource or a locally-installed externalapplication. In some cases, external applications 109 that are locallyinstalled on the client device 102 can be launched independently of andseparately from the messaging client 104, such as by selecting an icon,corresponding to the external application 109, on a home screen of theclient device 102. Small-scale versions of such external applicationscan be launched or accessed via the messaging client 104 and, in someexamples, no or limited portions of the small-scale external applicationcan be accessed outside of the messaging client 104. The small-scaleexternal application can be launched by the messaging client 104receiving, from a external app(s) server 110, a markup-language documentassociated with the small-scale external application and processing sucha document.

In response to determining that the external resource is alocally-installed external application 109, the messaging client 104instructs the client device 102 to launch the external application 109by executing locally-stored code corresponding to the externalapplication 109. In response to determining that the external resourceis a web-based resource, the messaging client 104 communicates with theexternal app(s) servers 110 to obtain a markup-language documentcorresponding to the selected resource. The messaging client 104 thenprocesses the obtained markup-language document to present the web-basedexternal resource within a user interface of the messaging client 104.

The messaging client 104 can notify a user of the client device 102, orother users related to such a user (e.g., “friends”), of activity takingplace in one or more external resources. For example, the messagingclient 104 can provide participants in a conversation (e.g., a chatsession) in the messaging client 104 with notifications relating to thecurrent or recent use of an external resource by one or more members ofa group of users. One or more users can be invited to join in an activeexternal resource or to launch a recently-used but currently inactive(in the group of friends) external resource. The external resource canprovide participants in a conversation, each using a respectivemessaging client messaging clients 104, with the ability to share anitem, status, state, or location in an external resource with one ormore members of a group of users into a chat session. The shared itemmay be an interactive chat card with which members of the chat caninteract, for example, to launch the corresponding external resource,view specific information within the external resource, or take themember of the chat to a specific location or state within the externalresource. Within a given external resource, response messages can besent to users on the messaging client 104. The external resource canselectively include different media items in the responses, based on acurrent context of the external resource.

The messaging client 104 can present a list of the available externalresources (e.g., third-party or external applications 109 or applets) toa user to launch or access a given external resource. This list can bepresented in a context-sensitive menu. For example, the iconsrepresenting different ones of the external application 109 (or applets)can vary based on how the menu is launched by the user (e.g., from aconversation interface or from a non-conversation interface).

System Architecture

FIG. 2 is a block diagram illustrating further details regarding themessaging system 100, according to some examples. Specifically, themessaging system 100 is shown to comprise the messaging client 104 andthe application servers 114. The messaging system 100 embodies a numberof subsystems, which are supported on the client side by the messagingclient 104 and on the sever side by the application servers 114. Thesesubsystems include, for example, an ephemeral timer system 202, acollection management system 204, an augmentation system 208, a mapsystem 210, a game system 212, and an external resource system 220.

The ephemeral timer system 202 is responsible for enforcing thetemporary or time-limited access to content by the messaging client 104and the messaging server 118. The ephemeral timer system 202incorporates a number of timers that, based on duration and displayparameters associated with a message, or collection of messages (e.g., astory), selectively enable access (e.g., for presentation and display)to messages and associated content via the messaging client 104. Furtherdetails regarding the operation of the ephemeral timer system 202 areprovided below.

The collection management system 204 is responsible for managing sets orcollections of media (e.g., collections of text, image video, and audiodata). A collection of content (e.g., messages, including images, video,text, and audio) may be organized into an “event gallery” or an “eventstory” Such a collection may be made available for a specified timeperiod, such as the duration of an event to which the content relates.For example, content relating to a music concert, may be made availableas a “story” for the duration of that music concert. The collectionmanagement system 204 may also be responsible for publishing an iconthat provides notification of the existence of a particular collectionto the user interface of the messaging client 104.

The collection management system 204 furthermore includes a curationinterface 206 that allows a collection manager to manage and curate aparticular collection of content. For example, the curation interface206 enables an event organizer to curate a collection of contentrelating to a specific event (e.g., delete inappropriate content orredundant messages). Additionally, the collection management system 204employs machine vision (or image recognition technology) and contentrules to automatically curate a content collection. In certain examples,compensation may be paid to a user for the inclusion of user-generatedcontent into a collection. In such cases, the collection managementsystem 204 operates to automatically make payments such users for theuse of their content.

The augmentation system 208 provides various functions that enable auser to augment (e.g., annotate or otherwise modify or edit) mediacontent associated with a message. For example, the augmentation system208 provides functions related to the generation and publishing of mediaoverlays for messages processed by the messaging system 100. Theaugmentation system 208 operatively supplies a media overlay oraugmentation (e.g., an image filter) to the messaging client 104 basedon a geolocation of the client device 102. In another example, theaugmentation system 208 operatively supplies a media overlay to themessaging client 104 based on other information, such as social networkinformation of the user of the client device 102. A media overlay mayinclude audio and visual content and visual effects. Examples of audioand visual content include pictures, texts, logos, animations,whole-body outfits, and sound effects. An example of a visual effectincludes color overlaying. The audio and visual content or the visualeffects can be applied to a media content item (e.g., a photo) at theclient device 102. For example, the media overlay may include text, agraphical element, or image that can be overlaid on top of a photographtaken by the client device 102. In another example, the media overlayincludes an identification of a location overlay (e.g., Venice beach), aname of a live event, or a name of a merchant overlay (e.g., BeachCoffee House). In another example, the augmentation system 208 uses thegeolocation of the client device 102 to identify a media overlay thatincludes the name of a merchant at the geolocation of the client device102. The media overlay may include other indicia associated with themerchant. The media overlays may be stored in the database 126 andaccessed through the database server 120.

In some examples, the augmentation system 208 provides a user-basedpublication platform that enables users to select a geolocation on a mapand upload content associated with the selected geolocation. The usermay also specify circumstances under which a particular media overlayshould be offered to other users. The augmentation system 208 generatesa media overlay that includes the uploaded content and associates theuploaded content with the selected geolocation.

In other examples, the augmentation system 208 provides a merchant-basedpublication platform that enables merchants to select a particular mediaoverlay associated with a geolocation via a bidding process. Forexample, the augmentation system 208 associates the media overlay of thehighest bidding merchant with a corresponding geolocation for apredefined amount of time. The augmentation system 208 communicates withthe image processing server 122 to obtain augmented reality experiencesand presents identifiers of such experiences in one or more userinterfaces (e.g., as icons over a real-time image or video or asthumbnails or icons in interfaces dedicated for presented identifiers ofaugmented reality experiences). Once an augmented reality experience isselected, one or more images, videos, or augmented reality graphicalelements are retrieved and presented as an overlay on top of the imagesor video captured by the client device 102. In some cases, the camera isswitched to a front-facing view (e.g., the front-facing camera of theclient device 102 is activated in response to activation of a particularaugmented reality experience) and the images from the front-facingcamera of the client device 102 start being displayed on the clientdevice 102 instead of the rear-facing camera of the client device 102.The one or more images, videos, or augmented reality graphical elementsare retrieved and presented as an overlay on top of the images that arecaptured and displayed by the front-facing camera of the client device102.

The map system 210 provides various geographic location functions, andsupports the presentation of map-based media content and messages by themessaging client 104. For example, the map system 210 enables thedisplay of user icons or avatars (e.g., stored in profile data 316) on amap to indicate a current or past location of “friends” of a user, aswell as media content (e.g., collections of messages includingphotographs and videos) generated by such friends, within the context ofa map. For example, a message posted by a user to the messaging system100 from a specific geographic location may be displayed within thecontext of a map at that particular location to “friends” of a specificuser on a map interface of the messaging client 104. A user canfurthermore share his or her location and status information (e.g.,using an appropriate status avatar) with other users of the messagingsystem 100 via the messaging client 104, with this location and statusinformation being similarly displayed within the context of a mapinterface of the messaging client 104 to selected users.

The game system 212 provides various gaming functions within the contextof the messaging client 104. The messaging client 104 provides a gameinterface providing a list of available games (e.g., web-based games orweb-based applications) that can be launched by a user within thecontext of the messaging client 104, and played with other users of themessaging system 100. The messaging system 100 further enables aparticular user to invite other users to participate in the play of aspecific game, by issuing invitations to such other users from themessaging client 104. The messaging client 104 also supports both voiceand text messaging (e.g., chats) within the context of gameplay,provides a leaderboard for the games, and also supports the provision ofin-game rewards (e.g., coins and items).

The external resource system 220 provides an interface for the messagingclient 104 to communicate with external app(s) servers 110 to launch oraccess external resources. Each external resource (apps) server 110hosts, for example, a markup language (e.g., HTML5) based application orsmall-scale version of an external application (e.g., game, utility,payment, or ride-sharing application that is external to the messagingclient 104). The messaging client 104 may launch a web-based resource(e.g., application) by accessing the HTML5 file from the externalresource (apps) servers 110 associated with the web-based resource. Incertain examples, applications hosted by external resource servers 110are programmed in JavaScript leveraging a Software Development Kit (SDK)provided by the messaging server 118. The SDK includes ApplicationProgramming Interfaces (APIs) with functions that can be called orinvoked by the web-based application. In certain examples, the messagingserver 118 includes a JavaScript library that provides a giventhird-party resource access to certain user data of the messaging client104. HTML5 is used as an example technology for programming games, butapplications and resources programmed based on other technologies can beused.

In order to integrate the functions of the SDK into the web-basedresource, the SDK is downloaded by an external resource (apps) server110 from the messaging server 118 or is otherwise received by theexternal resource (apps) server 110. Once downloaded or received, theSDK is included as part of the application code of a web-based externalresource. The code of the web-based resource can then call or invokecertain functions of the SDK to integrate features of the messagingclient 104 into the web-based resource.

The SDK stored on the messaging server 118 effectively provides thebridge between an external resource (e.g., third-party or externalapplications 109 or applets and the messaging client 104). This providesthe user with a seamless experience of communicating with other users onthe messaging client 104, while also preserving the look and feel of themessaging client 104. To bridge communications between an externalresource and a messaging client 104, in certain examples, the SDKfacilitates communication between external resource servers 110 and themessaging client 104. In certain examples, a WebViewJavaScriptBridgerunning on a client device 102 establishes two one-way communicationchannels between an external resource and the messaging client 104.Messages are sent between the external resource and the messaging client104 via these communication channels asynchronously. Each SDK functioninvocation is sent as a message and callback. Each SDK function isimplemented by constructing a unique callback identifier and sending amessage with that callback identifier.

By using the SDK, not all information from the messaging client 104 isshared with external resource servers 110. The SDK limits whichinformation is shared based on the needs of the external resource. Incertain examples, each external resource server 110 provides an HTML5file corresponding to the web-based external resource to the messagingserver 118. The messaging server 118 can add a visual representation(such as a box art or other graphic) of the web-based external resourcein the messaging client 104. Once the user selects the visualrepresentation or instructs the messaging client 104 through a GUI ofthe messaging client 104 to access features of the web-based externalresource, the messaging client 104 obtains the HTML5 file andinstantiates the resources necessary to access the features of theweb-based external resource.

The messaging client 104 presents a graphical user interface (e.g., alanding page or title screen) for an external resource. During, before,or after presenting the landing page or title screen, the messagingclient 104 determines whether the launched external resource has beenpreviously authorized to access user data of the messaging client 104.In response to determining that the launched external resource has beenpreviously authorized to access user data of the messaging client 104,the messaging client 104 presents another graphical user interface ofthe external resource that includes functions and features of theexternal resource. In response to determining that the launched externalresource has not been previously authorized to access user data of themessaging client 104, after a threshold period of time (e.g., 3 seconds)of displaying the landing page or title screen of the external resource,the messaging client 104 slides up (e.g., animates a menu as surfacingfrom a bottom of the screen to a middle of or other portion of thescreen) a menu for authorizing the external resource to access the userdata. The menu identifies the type of user data that the externalresource will be authorized to use. In response to receiving a userselection of an accept option, the messaging client 104 adds theexternal resource to a list of authorized external resources and allowsthe external resource to access user data from the messaging client 104.In some examples, the external resource is authorized by the messagingclient 104 to access the user data in accordance with an OAuth 2framework.

The messaging client 104 controls the type of user data that is sharedwith external resources based on the type of external resource beingauthorized. For example, external resources that include full-scaleexternal applications (e.g., a third-party or external application 109)are provided with access to a first type of user data (e.g., onlytwo-dimensional avatars of users with or without different avatarcharacteristics). As another example, external resources that includesmall-scale versions of external applications (e.g., web-based versionsof third-party applications) are provided with access to a second typeof user data (e.g., payment information, two-dimensional avatars ofusers, three-dimensional avatars of users, and avatars with variousavatar characteristics). Avatar characteristics include different waysto customize a look and feel of an avatar, such as different poses,facial features, clothing, and so forth.

Data Architecture

FIG. 3 is a schematic diagram illustrating data structures 300, whichmay be stored in the database 126 of the messaging server system 108,according to certain examples. While the content of the database 126 isshown to comprise a number of tables, it will be appreciated that thedata could be stored in other types of data structures (e.g., as anobject-oriented database).

The database 126 includes message data stored within a message table302. This message data includes, for any particular one message, atleast message sender data, message recipient (or receiver) data, and apayload. Further details regarding information that may be included in amessage, and included within the message data stored in the messagetable 302, is described below with reference to FIG. 4.

An entity table 306 stores entity data, and is linked (e.g.,reverentially) to an entity graph 308 and profile data 316. Entities forwhich records are maintained within the entity table 306 may includeindividuals, corporate entities, organizations, objects, places, events,and so forth. Regardless of entity type, any entity regarding which themessaging server system 108 stores data may be a recognized entity. Eachentity is provided with a unique identifier, as well as an entity typeidentifier (not shown).

The entity graph 308 stores information regarding relationships andassociations between entities. Such relationships may be social,professional (e.g., work at a common corporation or organization)interested-based or activity-based, merely for example.

The profile data 316 stores multiple types of profile data about aparticular entity. The profile data 316 may be selectively used andpresented to other users of the messaging system 100, based on privacysettings specified by a particular entity. Where the entity is anindividual, the profile data 316 includes, for example, a username,telephone number, address, settings (e.g., notification and privacysettings), as well as a user-selected avatar representation (orcollection of such avatar representations). A particular user may thenselectively include one or more of these avatar representations withinthe content of messages communicated via the messaging system 100, andon map interfaces displayed by messaging clients 104 to other users. Thecollection of avatar representations may include “status avatars,” whichpresent a graphical representation of a status or activity that the usermay select to communicate at a particular time.

Where the entity is a group, the profile data 316 for the group maysimilarly include one or more avatar representations associated with thegroup, in addition to the group name, members, and various settings(e.g., notifications) for the relevant group.

The database 126 also stores augmentation data, such as overlays orfilters, in an augmentation table 310. The augmentation data isassociated with and applied to videos (for which data is stored in avideo table 304) and images (for which data is stored in an image table312).

Filters, in one example, are overlays that are displayed as overlaid onan image or video during presentation to a recipient user. Filters maybe of various types, including user-selected filters from a set offilters presented to a sending user by the messaging client 104 when thesending user is composing a message. Other types of filters includegeolocation filters (also known as geo-filters), which may be presentedto a sending user based on geographic location. For example, geolocationfilters specific to a neighborhood or special location may be presentedwithin a user interface by the messaging client 104, based ongeolocation information determined by a Global Positioning System (GPS)unit of the client device 102.

Another type of filter is a data filter, which may be selectivelypresented to a sending user by the messaging client 104, based on otherinputs or information gathered by the client device 102 during themessage creation process. Examples of data filters include currenttemperature at a specific location, a current speed at which a sendinguser is traveling, battery life for a client device 102, or the currenttime.

Other augmentation data that may be stored within the image table 312includes augmented reality content items (e.g., corresponding toapplying augmented reality experiences). An augmented reality contentitem or augmented reality item may be a real-time special effect andsound that may be added to an image or a video.

As described above, augmentation data includes augmented reality contentitems, overlays, image transformations, AR images, and similar termsthat refer to modifications that may be applied to image data (e.g.,videos or images). This includes real-time modifications, which modifyan image as it is captured using device sensors (e.g., one or multiplecameras) of a client device 102 and then displayed on a screen of theclient device 102 with the modifications. This also includesmodifications to stored content, such as video clips in a gallery thatmay be modified. For example, in a client device 102 with access tomultiple augmented reality content items, a user can use a single videoclip with multiple augmented reality content items to see how thedifferent augmented reality content items will modify the stored clip.For example, multiple augmented reality content items that applydifferent pseudorandom movement models can be applied to the samecontent by selecting different augmented reality content items for thecontent. Similarly, real-time video capture may be used with anillustrated modification to show how video images currently beingcaptured by sensors of a client device 102 would modify the captureddata. Such data may simply be displayed on the screen and not stored inmemory, or the content captured by the device sensors may be recordedand stored in memory with or without the modifications (or both). Insome systems, a preview feature can show how different augmented realitycontent items will look within different windows in a display at thesame time. This can, for example, enable multiple windows with differentpseudorandom animations to be viewed on a display at the same time.

Data and various systems using augmented reality content items or othersuch transform systems to modify content using this data can thusinvolve detection of objects (e.g., faces, hands, bodies, cats, dogs,surfaces, objects, etc.), tracking of such objects as they leave, enter,and move around the field of view in video frames, and the modificationor transformation of such objects as they are tracked. In variousexamples, different methods for achieving such transformations may beused. Some examples may involve generating a three-dimensional meshmodel of the object or objects, and using transformations and animatedtextures of the model within the video to achieve the transformation. Inother examples, tracking of points on an object may be used to place animage or texture (which may be two dimensional or three dimensional) atthe tracked position. In still further examples, neural network analysisof video frames may be used to place images, models, or textures incontent (e.g., images or frames of video). Augmented reality contentitems thus refer both to the images, models, and textures used to createtransformations in content, as well as to additional modeling andanalysis information needed to achieve such transformations with objectdetection, tracking, and placement.

Real-time video processing can be performed with any kind of video data(e.g., video streams, video files, etc.) saved in a memory of acomputerized system of any kind. For example, a user can load videofiles and save them in a memory of a device, or can generate a videostream using sensors of the device. Additionally, any objects can beprocessed using a computer animation model, such as a human's face andparts of a human body, animals, or non-living things such as chairs,cars, or other objects.

In some examples, when a particular modification is selected along withcontent to be transformed, elements to be transformed are identified bythe computing device, and then detected and tracked if they are presentin the frames of the video. The elements of the object are modifiedaccording to the request for modification, thus transforming the framesof the video stream. Transformation of frames of a video stream can beperformed by different methods for different kinds of transformation.For example, for transformations of frames mostly referring to changingforms of object's elements, characteristic points for each element of anobject are calculated (e.g., using an Active Shape Model (ASM) or otherknown methods). Then, a mesh based on the characteristic points isgenerated for each of the at least one element of the object. This meshis used in the following stage of tracking the elements of the object inthe video stream. In the process of tracking, the mentioned mesh foreach element is aligned with a position of each element. Then,additional points are generated on the mesh. A first set of first pointsis generated for each element based on a request for modification, and aset of second points is generated for each element based on the set offirst points and the request for modification. Then, the frames of thevideo stream can be transformed by modifying the elements of the objecton the basis of the sets of first and second points and the mesh. Insuch method, a background of the modified object can be changed ordistorted as well by tracking and modifying the background.

In some examples, transformations changing some areas of an object usingits elements can be performed by calculating characteristic points foreach element of an object and generating a mesh based on the calculatedcharacteristic points. Points are generated on the mesh, and thenvarious areas based on the points are generated. The elements of theobject are then tracked by aligning the area for each element with aposition for each of the at least one element, and properties of theareas can be modified based on the request for modification, thustransforming the frames of the video stream. Depending on the specificrequest for modification, properties of the mentioned areas can betransformed in different ways. Such modifications may involve changingcolor of areas; removing at least some part of areas from the frames ofthe video stream; including one or more new objects into areas which arebased on a request for modification; and modifying or distorting theelements of an area or object. In various examples, any combination ofsuch modifications or other similar modifications may be used. Forcertain models to be animated, some characteristic points can beselected as control points to be used in determining the entirestate-space of options for the model animation.

In some examples of a computer animation model to transform image datausing face detection, the face is detected on an image with use of aspecific face detection algorithm (e.g., Viola-Jones). Then, an ActiveShape Model (ASM) algorithm is applied to the face region of an image todetect facial feature reference points.

Other methods and algorithms suitable for face detection can be used.For example, in some examples, features are located using a landmark,which represents a distinguishable point present in most of the imagesunder consideration. For facial landmarks, for example, the location ofthe left eye pupil may be used. If an initial landmark is notidentifiable (e.g., if a person has an eyepatch), secondary landmarksmay be used. Such landmark identification procedures may be used for anysuch objects. In some examples, a set of landmarks forms a shape. Shapescan be represented as vectors using the coordinates of the points in theshape. One shape is aligned to another with a similarity transform(allowing translation, scaling, and rotation) that minimizes the averageEuclidean distance between shape points. The mean shape is the mean ofthe aligned training shapes.

In some examples, a search for landmarks from the mean shape aligned tothe position and size of the face determined by a global face detectoris started. Such a search then repeats the steps of suggesting atentative shape by adjusting the locations of shape points by templatematching of the image texture around each point and then conforming thetentative shape to a global shape model until convergence occurs. Insome systems, individual template matches are unreliable, and the shapemodel pools the results of the weak template matches to form a strongeroverall classifier. The entire search is repeated at each level in animage pyramid, from coarse to fine resolution.

A transformation system can capture an image or video stream on a clientdevice (e.g., the client device 102) and perform complex imagemanipulations locally on the client device 102 while maintaining asuitable user experience, computation time, and power consumption. Thecomplex image manipulations may include size and shape changes, emotiontransfers (e.g., changing a face from a frown to a smile), statetransfers (e.g., aging a subject, reducing apparent age, changinggender), style transfers, graphical element application, and any othersuitable image or video manipulation implemented by a convolutionalneural network that has been configured to execute efficiently on theclient device 102.

In some examples, a computer animation model to transform image data canbe used by a system where a user may capture an image or video stream ofthe user (e.g., a selfie) using a client device 102 having a neuralnetwork operating as part of a messaging client 104 operating on theclient device 102. The transformation system operating within themessaging client 104 determines the presence of a face within the imageor video stream and provides modification icons associated with acomputer animation model to transform image data, or the computeranimation model can be present as associated with an interface describedherein. The modification icons include changes that may be the basis formodifying the user's face within the image or video stream as part ofthe modification operation. Once a modification icon is selected, thetransformation system initiates a process to convert the image of theuser to reflect the selected modification icon (e.g., generate a smilingface on the user). A modified image or video stream may be presented ina graphical user interface displayed on the client device 102 as soon asthe image or video stream is captured, and a specified modification isselected. The transformation system may implement a complexconvolutional neural network on a portion of the image or video streamto generate and apply the selected modification. That is, the user maycapture the image or video stream and be presented with a modifiedresult in real-time or near real-time once a modification icon has beenselected. Further, the modification may be persistent while the videostream is being captured, and the selected modification icon remainstoggled. Machine-taught neural networks may be used to enable suchmodifications.

The graphical user interface, presenting the modification performed bythe transformation system, may supply the user with additionalinteraction options. Such options may be based on the interface used toinitiate the content capture and selection of a particular computeranimation model (e.g., initiation from a content creator userinterface). In various examples, a modification may be persistent afteran initial selection of a modification icon. The user may toggle themodification on or off by tapping or otherwise selecting the face beingmodified by the transformation system and store it for later viewing orbrowse to other areas of the imaging application. Where multiple facesare modified by the transformation system, the user may toggle themodification on or off globally by tapping or selecting a single facemodified and displayed within a graphical user interface. In someexamples, individual faces, among a group of multiple faces, may beindividually modified, or such modifications may be individually toggledby tapping or selecting the individual face or a series of individualfaces displayed within the graphical user interface.

A story table 314 stores data regarding collections of messages andassociated image, video, or audio data, which are compiled into acollection (e.g., a story or a gallery). The creation of a particularcollection may be initiated by a particular user (e.g., each user forwhich a record is maintained in the entity table 306). A user may createa “personal story” in the form of a collection of content that has beencreated and sent/broadcast by that user. To this end, the user interfaceof the messaging client 104 may include an icon that is user-selectableto enable a sending user to add specific content to his or her personalstory.

A collection may also constitute a “live story,” which is a collectionof content from multiple users that is created manually, automatically,or using a combination of manual and automatic techniques. For example,a “live story” may constitute a curated stream of user-submitted contentfrom various locations and events. Users whose client devices havelocation services enabled and are at a common location event at aparticular time may, for example, be presented with an option, via auser interface of the messaging client 104, to contribute content to aparticular live story. The live story may be identified to the user bythe messaging client 104, based on his or her location. The end resultis a “live story” told from a community perspective.

A further type of content collection is known as a “location story,”which enables a user whose client device 102 is located within aspecific geographic location (e.g., on a college or university campus)to contribute to a particular collection. In some examples, acontribution to a location story may require a second degree ofauthentication to verify that the end user belongs to a specificorganization or other entity (e.g., is a student on the universitycampus).

As mentioned above, the video table 304 stores video data that, in oneexample, is associated with messages for which records are maintainedwithin the message table 302. Similarly, the image table 312 storesimage data associated with messages for which message data is stored inthe entity table 306. The entity table 306 may associate variousaugmentations from the augmentation table 310 with various images andvideos stored in the image table 312 and the video table 304.

Data Communications Architecture

FIG. 4 is a schematic diagram illustrating a structure of a message 400,according to some examples, generated by a messaging client 104 forcommunication to a further messaging client 104 or the messaging server118. The content of a particular message 400 is used to populate themessage table 302 stored within the database 126, accessible by themessaging server 118. Similarly, the content of a message 400 is storedin memory as “in-transit” or “in-flight” data of the client device 102or the application servers 114. A message 400 is shown to include thefollowing example components:

-   -   message identifier 402: a unique identifier that identifies the        message 400.    -   message text payload 404: text, to be generated by a user via a        user interface of the client device 102, and that is included in        the message 400.    -   message image payload 406: image data, captured by a camera        component of a client device 102 or retrieved from a memory        component of a client device 102, and that is included in the        message 400. Image data for a sent or received message 400 may        be stored in the image table 312.    -   message video payload 408: video data, captured by a camera        component or retrieved from a memory component of the client        device 102, and that is included in the message 400. Video data        for a sent or received message 400 may be stored in the video        table 304.    -   message audio payload 410: audio data, captured by a microphone        or retrieved from a memory component of the client device 102,        and that is included in the message 400.    -   message augmentation data 412: augmentation data (e.g., filters,        stickers, or other annotations or enhancements) that represents        augmentations to be applied to message image payload 406,        message video payload 408, or message audio payload 410 of the        message 400. Augmentation data for a sent or received message        400 may be stored in the augmentation table 310.    -   message duration parameter 414: parameter value indicating, in        seconds, the amount of time for which content of the message        (e.g., the message image payload 406, message video payload 408,        message audio payload 410) is to be presented or made accessible        to a user via the messaging client 104.    -   message geolocation parameter 416: geolocation data (e.g.,        latitudinal and longitudinal coordinates) associated with the        content payload of the message. Multiple message geolocation        parameter 416 values may be included in the payload, each of        these parameter values being associated with respect to content        items included in the content (e.g., a specific image within the        message image payload 406, or a specific video in the message        video payload 408).    -   message story identifier 418: identifier values identifying one        or more content collections (e.g., “stories” identified in the        story table 314) with which a particular content item in the        message image payload 406 of the message 400 is associated. For        example, multiple images within the message image payload 406        may each be associated with multiple content collections using        identifier values.    -   message tag 420: each message 400 may be tagged with multiple        tags, each of which is indicative of the subject matter of        content included in the message payload. For example, where a        particular image included in the message image payload 406        depicts an animal (e.g., a lion), a tag value may be included        within the message tag 420 that is indicative of the relevant        animal. Tag values may be generated manually, based on user        input, or may be automatically generated using, for example,        image recognition.    -   message sender identifier 422: an identifier (e.g., a messaging        system identifier, email address, or device identifier)        indicative of a user of the client device 102 on which the        message 400 was generated and from which the message 400 was        sent.    -   message receiver identifier 424: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of a user of the client device 102 to        which the message 400 is addressed.

The contents e.g., values) of the various components of message 400 maybe pointers to locations in tables within which content data values arestored. For example, an image value in the message image payload 406 maybe a pointer to (or address of) a location within an image table 312.Similarly, values within the message video payload 408 may point to datastored within a video table 304, values stored within the messageaugmentation data 412 may point to data stored in an augmentation table310, values stored within the message story identifier 418 may point todata stored in a story table 314, and values stored within the messagesender identifier 422 and the message receiver identifier 424 may pointto user records stored within an entity table 306.

Eyewear Device

FIG. 5 shows a front perspective view of an eyewear device 119 in theform of a pair of smart glasses that include a hands-free control system107 according to one example. The eyewear device 119 includes a body 503comprising a front piece or frame 506 and a pair of temples 509connected to the frame 506 for supporting the frame 506 in position on auser's face when the eyewear device 119 is worn. The frame 506 can bemade from any suitable material such as plastics or metal, including anysuitable shape memory alloy.

The eyewear device 119 includes a pair of optical elements in the formof a pair of lenses 512 held by corresponding optical element holders inthe form of a pair of rims 515 forming part of the frame 506. The rims515 are connected by a bridge 518. In other examples, one or both of theoptical elements can be a display, a display assembly, or a lens anddisplay combination.

The frame 506 includes a pair of end pieces 521 defining lateral endportions of the frame 506. In this example, a variety of electronicscomponents are housed in one or both of the end pieces 521. The temples509 are coupled to the respective end pieces 521. In this example, thetemples 509 are coupled to the frame 506 by respective hinges so as tobe hingedly movable between a wearable mode and a collapsed mode inwhich the temples 509 are pivoted towards the frame 506 to liesubstantially flat against it. In other examples, the temples 509 can becoupled to the frame 506 by any suitable means, or can be rigidly orfixedly secured to the frame 506 so as to be integral therewith.

Each of the temples 509 that includes a front portion of that is coupledto the frame 506 and any suitable rear portion for coupling to the earof the user, such as the curves or cute piece illustrated in the exampleof FIG. 5. In some examples, the frame 506 is formed of a single pieceof material, so as to have a unitary or monolithic construction. In someexamples, the whole of the body 503 (including both the frame 506 andthe temples 509) can be of the unitary or monolithic construction.

The eyewear device 119 has onboard electronics components including acomputing device, such as a computer 524, or low power processor, whichcan in different examples be of any suitable type so as to be carried bythe body 503. In some examples, the computer 524 is at least partiallyhoused in one or both of the temples 509. In the present example,various components of the computer 524 are housed in the lateral endpieces 521 of the frame 506. The computer 524 includes one or moreprocessors with memory (e.g., a volatile storage device, such as randomaccess memory or registers), a storage device (e.g., a non-volatilestorage device), wireless communication circuitry (e.g., BLEcommunication devices and/or WiFi direct devices), and a power source.The computer 524 comprises low-power circuitry, high-speed circuitry,and, in some examples, a display processor. Various examples may includethese elements in different configurations or integrated together indifferent ways.

The computer 524 additionally includes a battery 527 or other suitableportable power supply. In one example, the battery 527 is disposed inone of the temples 509. In the eyewear device 119 shown in FIG. 5, thebattery 527 is shown as being disposed in one of the end pieces 521,being electrically coupled to the remainder of the computer 524 housedin the corresponding end piece 521.

The eyewear device 119 is camera-enabled, in this example comprising acamera 530 mounted in one of the end pieces 521 and facing forwards soas to be aligned more or less with the direction of view of a wearer ofthe eyewear device 119. The camera 530 is configured to capture digitalimages (also referred to herein as digital photographs or pictures) aswell as digital video content. Operation of the camera 530 is controlledby a camera controller provided by the computer 524, image datarepresentative of images or video captured by the camera 530 beingtemporarily stored on a memory forming part of the computer 524. In someexamples, the eyewear device 119 can have a pair of cameras 530, e.g.housed by the respective end pieces 521.

As will be described in greater detail below, the onboard computer 524,camera 530, and the lenses 512 are configured together to provide ahands-free control system 107 that automatically activates a video clipcapture mode in which one or more video clip generation options aredisplayed when a static mirror is within view of the lenses 512. Thehands-free control system 107 allows the user to navigate through menuoptions (e.g., virtual or AR whole-body outfits, filters, video clipcapture and share functions) by using a reflection of one or morefingers of the hand in the static mirror captured by the camera 530 as acursor. Specifically, the lenses 512 can display virtual content or oneor more virtual objects (e.g., whole-body outfits) or menu options sothey appear in the reflection of the user in the static mirror. Thismakes it appear to the user that the reflection of the user in thestatic mirror includes the virtual content or one or more virtualobjects or menu options. The hands-free control system 107 detects adirection to which the one or more fingers of the user's hand arepointing within the reflection of the user in the static mirror andperforms selections between the displayed virtual content, objects ormenu options based on direction to which the one or more fingers arepointing. This gives the user the illusion that the user is interactingwith an electronic mirroring device. Namely, by wearing the eyeweardevice 119 and focusing on a static mirror, the user is given theimpression that the user is interacting with an electronic device thathas a front-facing camera and is displaying a video feed on the screenfacing the user.

Based on input received by the eyewear device 119 from the camera 530,the eyewear device 119 can control user interaction with the virtualcontent based on hand movement that appears in the reflection of theuser in the static mirror in the one or more images captured by thecamera 530. In one example, the user interaction can control video clipcapture. For example, the eyewear device 119 can capture a video clip ofthe reflection of the user in the static mirror having a duration set bythe options selected by the user using the hand as a cursor. In anotherexample, the user interaction can navigate through a video modificationoptions and video clip options. In another example, the user interactioncan navigate through a conversation the user is involved in, such as byscrolling through various three-dimensional or two-dimensionalconversation elements (e.g., chat bubbles) displayed in the lenses at aposition of the static mirror which reflects the user and selectingindividual conversation elements to respond to generate messages totransmit to participants of the conversation. In another example, theuser interaction can navigate through a one or more virtual or ARwhole-body outfits overlaid on the user and displayed in the lenses at aposition of the static mirror which reflects the user.

The eyewear device 119 further includes one or more communicationdevices, such as Bluetooth low energy (BLE) communication interface.Such BLE communication interface enables the eyewear device 119 tocommunicate wirelessly with the client device 102. Other forms ofwireless communication can also be employed instead of, or in additionto, the BLE communication interface, such as a WiFi direct interface.The BLE communication interface implements a standard number of BLEcommunication protocols.

A first of the communications protocols implemented by the BLE interfaceof the eyewear device 119 enables an unencrypted link to be establishedbetween the eyewear device 119 and the client device 102. In this firstprotocol, the link-layer communication (the physical interface ormedium) between the eyewear device 119 and the client device 102includes unencrypted data. In this first protocol, the application layer(the communication layer operating on the physically exchanged data)encrypts and decrypts data that is physically exchanged in unencryptedform over the link layer of the BLE communication interface. In thisway, data exchanged over the physical layer can freely be read by aneavesdropping device, but the eavesdropping device will not be able todecipher the data that is exchanged without performing a decryptionoperation in the application layer.

A second of the communications protocols implemented by the BLEinterface of the eyewear device 119 enables an encrypted link to beestablished between the eyewear device 119 and the client device 102. Inthis second protocol, the link-layer communication (the physicalinterface) between the eyewear device 119 and the client device 102receives data from the application layer and adds a first type ofencryption to the data before exchanging the data over the physicalmedium. In this second protocol, the application layer (thecommunication layer operating on the physically exchanged data) may ormay not use a second type of encryption to encrypt and decrypt data thatis physically exchanged in encrypted form, using the first type ofencryption, over the link layer of the BLE communication interface.Namely, data can be first encrypted by the application layer and then befurther encrypted by the physical layer before being exchanged over thephysical medium. Following the exchange over the physical medium, thedata is then decrypted by the physical layer and then decrypted again(e.g., using a different type of encryption) by the application layer.In this way, data exchanged over the physical layer cannot be read by aneavesdropping device as the data is encrypted in the physical medium.

In some examples, the client device 102 communicates with the eyeweardevice 119 using the first protocol to exchange images or videos orvirtual content between the messaging client 104 and the eyewear device119.

Electronic Mirroring Device

FIG. 6A is a diagrammatic representation of an electronic mirroringdevice 130 that includes a hands-free control system 107, in accordancewith some examples. The electronic mirroring device 130 includes afront-facing camera 610 (e.g., a red, green and blue camera), a depthsensor 620, a mirror, screen or display 640 (e.g., 1000+nits display),power and navigation buttons 660, a light-emitting diode (LED) light630, a communication device 661 (e.g., WiFi or Bluetooth), and a speakerand microphone 650. When operated by the hands-free control system 107,the functions and features of the electronic mirroring device 130 can becontrolled from up to and beyond 10 or more meters away from theelectronic mirroring device 130. Namely, a user can stand up to andbeyond 10 or more meters away from the electronic mirroring device 130and control and activate various features, functions and options tocapture a video clip or perform other operations.

The front-facing camera 610 captures an image or video and displays theimage or video that is captured on the display 640. In this way, thedisplay 640 when viewed by a user appears to be a mirror that reflectsan image of the user. Upon detecting a user by the front-facing camera610, facial or object recognition techniques can be employed to providea display on the screen of various user-specific options. As an example,the options can include video clip generation options or messaging orcommunication options.

The power and navigation buttons 660 can be used to turn ON/OFF theelectronic mirroring device 130. When turned OFF, the display 640 nolonger provides a reflection and instead is turned off and is blackedout. The electronic mirroring device 130 allows the user to interactwith options presented on the display 640 using the hand of the user asa cursor or by pointing one or more fingers of the hand in differentdirections. Namely, the hands-free control system 107 can detect andtrack movement of the user's hand and fingers of the hand captured bythe camera 610 and perform selections of different options that aredisplayed on the display 640. The user can alternatively performselections by physically interacting with the electronic mirroringdevice 130 and pressing the navigation buttons 660.

The LED light 630 is a light that is placed around the border of theelectronic mirroring device 130. The LED light 630 can be set to anydesired color. For example, a first user can set the LED light 630 to afirst color and a second user can set the LED light 630 to anothercolor. When facial recognition of the electronic mirroring device 130detects the first user within the view of the camera 610, the electronicmirroring device 130 activates the LED light 630 and sets the light tothe first color. When facial recognition of the electronic mirroringdevice 130 detects the second user within the view of the camera 610after detecting the first user, the electronic mirroring device 130transitions the LED light 630 from the first color to the second color.The brightness of the LED light 630 can continuously transition from afirst brightness setting to a second brightness setting to simulateanimation of the LED light 630. In some cases, the LED light 630 can beset to a static brightness setting. When a given user is detected withinview of the camera 610, the brightness of the LED light 630 can startbeing animated by transitioning between different brightness settingscontinuously.

The LED light 630 can be integrated or implemented as part of the screenof the electronic mirroring device 130 rather than being implemented bya physical LED light. For example, a set of pixels around a border ofthe screen of the electronic mirroring device 130 can be set to aspecified brightness and color to mimic the function of the LED light630. When a front-facing camera 610 is turned on and a video clip is setto be captured by the front-facing camera 610, the set of pixels aroundthe border of the screen can be activated to illuminate the on-screenbuttons and improve the quality and brightness of the video feed backcaptured. The LED light 630 (implemented as a border of pixels or asphysical LED lights around the electronic mirroring device 130) improvesthe ability of the electronic mirroring device 130 in track a positionof the user's body, hand, body parts or fingers to enable remote controlof the electronic mirroring device 130. As discussed above, the LEDlight 630 (light around the border of the electronic mirroring device130) can be activated or turned ON in response to activating ahands-free mode of operating the electronic mirroring device 130, suchas when a set of conditions for activating the hands-free mode ofoperation are satisfied.

The communication device 661 allows the electronic mirroring device 130to send and receive audio/video to/from other users. In one example, theelectronic mirroring device 130 can capture a video clip and send thevideo clip to one or more other users through the communication device661. The communication device 661 can also include cellular technologyallowing a user to place phone calls to other users. The speaker andmicrophone 650 can receive verbal commands from the user to control theelectronic mirroring device 130 and to talk with other users. Thespeaker and microphone 650 can be used to capture audio while capturingvideo of the user to generate a video clip. The speaker and microphone650 can be used to output audio of a video clip received by the user.

FIG. 6B is a diagrammatic representation of the electronic mirroringdevice 130 that includes a hands-free control system 107, in accordancewith some examples. As shown, the electronic mirroring device 130 is astationary device that stands on a floor of a household or otherphysical establishment. In this example, the electronic mirroring device130 has a height 690 that is greater than a height 692 of an averageuser (e.g., the height is greater than 5 feet or 6 feet). It is to beunderstood that other sized electronic mirroring devices can be used inexample embodiments. The electronic mirroring device 130 provides in thedisplay screen 682 a reflection of the user as captured by the camera610 of the electronic mirroring device 130. The electronic mirroringdevice 130 presents one or more options 680 through which the user cannavigate using the user's hand as a cursor or by pointing one or morefingers of the hand in different directions, as controlled by thehands-free control system 107.

Hands-Free Control System

FIG. 7 is a flowchart illustrating example operations of the hands-freecontrol system 107 in performing a process 700, according to exampleexamples. The process 700 may be embodied in computer-readableinstructions for execution by one or more processors such that theoperations of the process 700 may be performed in part or in whole bythe functional components of the hands-free control system 107;accordingly, the process 700 is described below by way of example withreference thereto. However, in other examples, at least some of theoperations of the process 700 may be deployed on various other hardwareconfigurations. The process 700 is therefore not intended to be limitedto the hands-free control system 107 and can be implemented in whole, orin part, by any other component. Some or all of the operations ofprocess 700 can be in parallel, out of order, or entirely omitted.

At operation 701, the hands-free control system 107 captures a videofeed received from a camera of the electronic mirroring device, thevideo feed depicting a user. For example, as shown in FIG. 6B, theelectronic mirroring device 130 displays a video feed of the user on ascreen 682 based on images captured by the front-facing camera of theelectronic mirroring device 130. In some cases, the video is captured bya camera of an eyewear device 119 focused on a static mirror thatreflects an image of the user.

At operation 702, the hands-free control system 107 evaluates a set ofconditions for activating a hands-free mode of operating the electronicmirroring device 130. For example, the hands-free control system 107determines that the video feed is being received from a front-facingcamera of the electronic mirroring device 130 and that the front-facingcamera has remained static (e.g., has not been moved by more than athreshold amount) over a given time interval. The hands-free controlsystem 107 determines that an on-screen option associated withhands-free operations (e.g., an on-screen video clip capture option oran augmented reality experience option) has been physically selected bytouching the screen of the electronic mirroring device 130. Thehands-free control system 107 then analyzes a camera feed to detectpresence of a whole-body of the user. In response to detecting presenceof the whole-body of the user, the hands-free control system 107determines that the set of conditions for activating the hands-free modeof operating the electronic mirroring device 130 has been satisfied.

At operation 703, the hands-free control system 107 activates thehands-free mode of operating the electronic mirroring device 130. Forexample, the electronic mirroring device 130 can modify or increase adisplay attribute of a display of the electronic mirroring device 130.For example, the hands-free control system 107 can increase a brightnessof the display, increase a size of one or more graphical elements thatare displayed on the display, such as one or more menu. options, oractivate a light (e.g., an LED light 630) that is provided and disposedaround a border of the electronic mirroring device 130, or combinationthereof. The hands-free control system 107 can then display one or moremenu options on the display of the electronic mirroring device 130 orwithin lenses of the eyewear device 119.

At operation 704, the hands-free control system 107 performs one or morefunctions on the electronic mirroring device 130 based on detecting oneor more gestures performed by the user in the video feed, as explainedabove and below. For example, the hands-free control system 107 cancontrol capture of a video clip of the user, access communicationfeatures (e.g., compose and response to chat messages), play and controlmusic or video, activate one or more augmented reality experiences,control and activate a gaming application, or any combination thereof.

FIGS. 8A, 8B and 9 are illustrative screens of a graphical userinterface of the hands-free control system 107 according to exampleexamples. The screens shown in FIGS. 8A, 8B and 9 may be provided by themessaging client 104 of one or more client devices 102, the hands-freecontrol system 107, other applications implemented on one or more clientdevices 102, the electronic mirroring device 130, the eyewear device119, or any combination thereof.

For example, the screen 800 of FIG. 8A shows a screen of an electronicmirroring device 130 in which a video feed of a user 810 captured by thefront-facing camera is shown. Specifically, a user 810 can be standingin front of the electronic mirroring device 130. The camera of theelectronic mirroring device 130 captures an image of the user anddisplays the image as the user's reflection.

The hands-free control system 107 can display a plurality of augmentedreality experience options 830. Each of the plurality of augmentedreality experience options 830 causes a different set of one or moreaugmented reality elements to be displayed and animated on the videofeed. In some cases, the hands-free control system 107 display a videoclip capture option. In response to receiving a user selection of agiven augmented reality experience option 832 or a hands-free basedvideo clip capture option (as discussed in detail below), the hands-freecontrol system 107 evaluates a set of conditions for activatinghands-free operations of the electronic mirroring device 130.

For example, the hands-free control system 107 can determine that thevideo feed of the user 810 is being captured by the front-facing cameraof the electronic mirroring device 130 as one of the set of conditions.The hands-free control system 107 can determine that physical movementof the front-facing camera does not exceed a threshold amount ofmovement as another one of the set of conditions. To do so, thehands-free control system 107 can access a gyroscopic component andobtain measurements from the gyroscopic component indicating movement ofthe electronic mirroring device 130. If the measurements do not vary bymore than a threshold amount (e.g., 2 millimeters) over a given timeperiod (e.g., 2 seconds), the hands-free control system 107 determinesthat the front-facing camera does not exceed the threshold amount.

In some examples, the hands-free control system 107 can determinepresence of a whole body of the user 810 in the camera feed as anotherone of the set of conditions. While the hands-free control system 107 issearching for the presence of the whole body of the user 810 in thecamera feed (or video feed), the hands-free control system 107 candisplay an indicator or animated indicator 820. The indicator oranimated indicator 820 can inform the user 810 that a search for thewhole body of the user is being performed. In some implementations, thehands-free control system 107 can perform object recognition on thecaptured video feed to detect presence of one or more skeletal joints ofa user. In response to determining that the detected skeletal jointsmatch a predetermined combination of skeletal joints (e.g., acombination of a head joint, shoulder joints, and arm joints; acombination of shoulder joints and a hip joint; or a combination of ahead joint, shoulder joints, hip joints, and leg joints), the hands-freecontrol system 107 determines that the whole body of the user 810 ispresent in the camera feed.

In some implementations, the hands-free control system 107 can determinethat presence of the whole body of the user 810 has not been detected inthe video feed within a threshold period of time (e.g., within the past5 seconds). In response, the hands-free control system 107 can replacethe indicator or animated indicator 820 with an instructional indicator860, as shown in FIG. 8B. The instructional indicator 860 can instructthe user 810 to move further away from the electronic mirroring device130 in order for a greater number of skeletal joints to be detected inthe camera feed. For example, if the hands-free control system 107detects only the head and shoulder joints in the camera feed over thetime period of five seconds, the hands-free control system 107 caninstruct the user 810 to move further away from the camera by displayingthe instructional indicator 860. After the user moves further away fromthe camera, as shown in FIG. 8B, additional skeletal joints of the user850 start to appear in the camera feed. For example, the hands-freecontrol system 107 can now determine that the head and shoulder jointsare detected by the object recognize in addition to the arm, hip and legjoints. The hands-free control system 107 can determine that thecombination of joints that appear in the camera feed match apredetermined combination of joints. In response, the hands-free controlsystem 107 determines that a whole body of the user is detected in thecamera feed and activates automatically the hands-free operating mode ofthe electronic mirroring device 130.

After activating the hands-free operating mode, the hands-free controlsystem 107 displays a set of options, such as the options shown in theinterface 900 of FIG. 9. Specifically, as shown in screen 930, thehands-free control system 107 displays a menu tray or options region934. The options region 934 includes a set of options for creating,editing and sharing video clips or images, such as by applying one ormore filters or augmented reality elements. Other options besides thoseshown can also be provided, such as messaging options, media navigationoptions, video/image modification options, communication interfaceoptions, and so forth. The options region 934 that is shown in thisexample includes one or more filter options. The options regions 934 caninclude an undo video clip option, when selected, deletes the previouslycaptured video clip or one or more segments of one or more previouslycaptured video clips; a video clip generation option, when selected,triggers the capture and recording of a video clip based on the videofeed received by the front-facing camera of a specified duration (e.g.,5 second video clip); and a share video clip option, when selected,causes a list of recipients to be presented to the user. The hands-freecontrol system 107 receives a selection of one or more recipients fromthe user (e.g., based on a direction to which one or more fingers arepointing) and then sends the last captured video clip or video clipsegments to the designated recipients.

In some examples, the hands-free control system 107 displays an exitoption (not shown) after activating the hands-free mode of operation. Inresponse to determining that the exit option is selected during thehands free mode of operation (e.g. by detecting that a finger of theuser points to the option for a threshold period of time or that aposition of the hand of the user in the video feed overlaps a displayposition of the exit option for the threshold period of time), thehands-free control system 107 terminates the hands free mode ofoperation. In this case, selection of any on-screen options can only beperformed by physically touching the option on the screen of theelectronic mirroring device 130.

In some cases, when the hands free mode of operation of the electronicmirroring device 130 is activated, a first set of options that aredisplayed on the screen of the electronic mirroring device 130 can beselected only by gestures of the user (e.g., by detecting that a fingerof the user's hand points to the option in the video feed or bydetecting that a hand of the user in the camera feed overlaps a displayposition of the option). In such circumstances, such options cannot beselected or activated by physically touching the screen of theelectronic mirroring device 130. A second set of options (which can bedisplayed together with the first set of options) can be selected onlyby physically touching the screen of the electronic mirroring device 130and are not activated and cannot be selected based on gestures performedby the user in the camera feed. A third set of options can be selectedeither by physically touching the screen of the electronic mirroringdevice 130 or by gestures of the user (e.g., by detecting that a fingerof the user's hand points to the option in the video feed or bydetecting that a hand of the user in the camera feed overlaps a displayposition of the option). The first, second and third sets of options canbe visually distinguished on the screen (e.g., displayed in differentcolors, sizes, shapes, and so forth) to indicate the manner in whichthey can be selected. The first set of options can include options forcontrolling capture of a video clip, the second set of options caninclude options for controlling an operating system or otherapplications of the electronic mirroring device 130 (e.g., applicationsother than the messaging client 104), and the third set of options caninclude options for controlling other operations (e.g., communicationfunctions, avatar selection, search operations, and so forth) of themessaging client 104.

The hands-free control system 107 detects one or more fingers 932 of ahand of the user in the video feed. The hands-free control system 107determines that one or more fingers 932 are pointing in a particulardirection. For example, the hands-free control system 107 generates avirtual line 939 that extends from the one or more fingers 932 and runsparallel to the one or more fingers 932. The hands-free control system107 determines whether the virtual line 939 intersects a displayposition of a given one of the options in the options region 934. Inresponse, the hands-free control system 107 increases a size of an icon936 relative to other icons shown in the options region 934 to indicatewhich icon is being identified by the direction to which the one or morefingers 932 are pointing.

The hands-free control system 107 determines that the identified menuoption remains identified by the one or more fingers 932 (e.g., thehands-free control system 107 determines that the one or more fingersremain pointed at and in a direction that a virtual line 939 continuesto intersect the display position of the identified menu option) for athreshold period of time (e.g., 3 seconds or more). In response, thehands-free control system 107 activates a function corresponding to theidentified menu option (e.g., plays/pauses playback of music or video,activates a video clip capture function, overlays one or more filters onthe video feed, captures an image, activates one or more augmentedreality experiences or elements).

Machine Architecture

FIG. 10 is a diagrammatic representation of the machine 1000 withinwhich instructions 1008 (e.g., software, a program, an application, anapples, an app, or other executable code) for causing the machine 1000to perform any one or more of the methodologies discussed herein may beexecuted. For example, the instructions 1008 may cause the machine 1000to execute any one or more of the methods described herein. Theinstructions 1008 transform the general, non-programmed machine 1000into a particular machine 1000 programmed to carry out the described andillustrated functions in the manner described. The machine 1000 mayoperate as a standalone device or may be coupled (e.g., networked) toother machines. In a networked deployment, the machine 1000 may operatein the capacity of a server machine or a client machine in aserver-client network environment, or as a peer machine in apeer-to-peer (or distributed) network environment. The machine 1000 maycomprise, but not be limited to, a server computer, a client computer, apersonal computer (PC), a tablet computer, a laptop computer, a netbook,a set-top box (STB), a personal digital assistant (PDA), anentertainment media system, a cellular telephone, a smartphone, a mobiledevice, a wearable device (e.g., a smartwatch), a smart home device(e.g., a smart appliance), other smart devices, a web appliance, anetwork router, a network switch, a network bridge, or any machinecapable of executing the instructions 1008, sequentially or otherwise,that specify actions to be taken by the machine 1000. Further, whileonly a single machine 1000 is illustrated, the term “machine” shall alsobe taken to include a collection of machines that individually orjointly execute the instructions 1008 to perform any one or more of themethodologies discussed herein. The machine 1000, for example, maycomprise the client device 102 or any one of a number of server devicesforming part of the messaging server system 108. In some examples, themachine 1000 may also comprise both client and server systems, withcertain operations of a particular method or algorithm being performedon the server-side and with certain operations of the particular methodor algorithm being performed on the client-side.

The machine 1000 may include processors 1002, memory 1004, andinput/output (I/O) components 1038, which may be configured tocommunicate with each other via a bus 1040.

For example, the frameworks 1108 providevarious graphical user interface (GUI) functions, high-level resourcemanagement, and high-level location services. The frameworks 1108 canprovide a broad spectrum of other APIs that can be used by theapplications 1106, some of which may be specific to a particularoperating system or platform.

In an example, the applications 1106 may include a home application1136, a contacts application 1130, a browser application 1132, a bookreader application 1134, a location application 1142, a mediaapplication 1144, a messaging application 1146, a game application 1148,and a broad assortment of other applications such as an externalapplication 1140.

The access time for the ephemeralmessage may be set by the message sender. Alternatively, the access timemay be a default setting or a setting specified by the recipient.Regardless of the setting technique, the message is transitory.

“MACHINE-READABLE MEDIUM” in this context refers to a component, device,or other tangible media able to store instructions and data temporarilyor permanently and may include, but is not limited to, random-accessmemory (RAM), read-only memory (ROM), buffer memory, flash memory,optical media, magnetic media, cache memory, other types of storage(e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/or anysuitable combination thereof. The term “machine-readable medium” shouldbe taken to include a single medium or multiple media (e.g., acentralized or distributed database, or associated caches and servers)able to store instructions. The term “machine-readable medium” shallalso be taken to include any medium, or combination of multiple media,that is capable of storing instructions (e.g., code) for execution by amachine, such that the instructions, when executed by one or moreprocessors of the machine, cause the machine to perform any one or moreof the methodologies described herein. Accordingly, a “machine-readablemedium” refers to a single storage apparatus or device, as well as“cloud-based” storage systems or storage networks that include multiplestorage apparatus or devices. The term “machine-readable medium”excludes signals per se.

“COMPONENT” in this context refers to a device, physical entity, orlogic having boundaries defined by function or subroutine calls, branchpoints, APIs, or other technologies that provide for the partitioning ormodularization of particular processing or control functions. Componentsmay be combined via their interfaces with other components to carry outa machine process. A component may be a packaged functional hardwareunit designed for use with other components and a part of a program thatusually performs a particular function of related functions. Componentsmay constitute either software components (e.g., code embodied on amachine-readable medium) or hardware components. A “hardware component”is a tangible unit capable of performing certain operations and may beconfigured or arranged in a certain physical manner. In various exampleexamples, one or more computer systems (e.g., a standalone computersystem, a client computer system, or a server computer system) or one ormore hardware components of a computer system (e.g., a processor or agroup of processors) may be configured by software (e.g., an applicationor application portion) as a hardware component that operates to performcertain operations as described herein.

A hardware component may also be implemented mechanically,electronically, or any suitable combination thereof. For example, ahardware component may include dedicated circuitry or logic that ispermanently configured to perform certain operations. A hardwarecomponent may be a special-purpose processor, such as aField-Programmable Gate Array (FPGA) or an ASIC. A hardware componentmay also include programmable logic or circuitry that is temporarilyconfigured by software to perform certain operations. For example, ahardware component may include software executed by a general-purposeprocessor or other programmable processor. Once configured by suchsoftware, hardware components become specific machines (or specificcomponents of a machine) uniquely tailored to perform the configuredfunctions and are no longer general-purpose processors. It will beappreciated that the decision to implement a hardware componentmechanically, in dedicated and permanently configured circuitry, or intemporarily configured circuitry (e.g., configured by software) may bedriven by cost and time considerations. Accordingly, the phrase“hardware component”(or “hardware-implemented component”) should beunderstood to encompass a tangible entity, be that an entity that isphysically constructed, permanently configured hardwired), ortemporarily configured (e.g., programmed) to operate in a certain manneror to perform certain operations described herein. Considering examplesin which hardware components are temporarily configured (e.g.,programmed), each of the hardware components need not be configured orinstantiated at any one instance in time. For example, where a hardwarecomponent comprises a general-purpose processor configured by softwareto become a special-purpose processor, the general-purpose processor maybe configured as respectively different special-purpose processors(e.g., comprising different hardware components) at different times.Software accordingly configures a particular processor or processors,for example, to constitute a particular hardware component at oneinstance of time and to constitute a different hardware component at adifferent instance of time.

Hardware components can provide information to, and receive informationfrom, other hardware components. Accordingly, the described hardwarecomponents may be regarded as being communicatively coupled. Wheremultiple hardware components exist contemporaneously, communications maybe achieved through signal transmission (e.g., over appropriate circuitsand buses) between or among two or more of the hardware components. Inexamples in which multiple hardware components are configured orinstantiated at different times, communications between such hardwarecomponents may be achieved, for example, through the storage andretrieval of information in memory structures to which the multiplehardware components have access. For example, one hardware component mayperform an operation and store the output of that operation in a memorydevice to which it is communicatively coupled. A further hardwarecomponent may then, at a later time, access the memory device toretrieve and process the stored output.

Hardware components may also initiate communications with input oroutput devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an API). The performance ofcertain of the operations may be distributed among the processors, notonly residing within a single machine, but deployed across a number ofmachines. In some example examples, the processors orprocessor-implemented components may be located in a single geographiclocation (e.g., within a home environment, an office environment, or aserver farm). In other example examples, the processors orprocessor-implemented components may be distributed across a number ofgeographic locations.

“PROCESSOR” in this context refers to any circuit or virtual circuit (aphysical circuit emulated by logic executing on an actual processor)that manipulates data values according to control signals (e.g.,“commands,” “op codes,” “machine code,”, etc.) and which producescorresponding output signals that are applied to operate a machine. Aprocessor may, for example, be a Central Processing Unit (CPU), aReduced Instruction Set Computing (RISC) processor, a ComplexInstruction Set Computing (CISC) processor, a Graphics Processing Unit(GPU), a Digital Signal Processor (DSP), an ASIC a Radio-FrequencyIntegrated Circuit (RFIC) or any combination thereof. A processor mayfurther be a multi-core processor having two or more independentprocessors (sometimes referred to as “cores”) that may executeinstructions contemporaneously.

Changes and modifications may be made to the disclosed examples withoutdeparting from the scope of the present disclosure. These and otherchanges or modifications are intended to be included within the scope ofe present disclosure, as expressed in the following claims.

Modules, Components, and Logic

Certain examples are described herein as including logic or a number ofcomponents, modules, or mechanisms. Modules can constitute eithersoftware modules (e,g., code embodied on a machine-readable medium or ina transmission signal) or hardware modules. A “hardware module” is atangible unit capable of performing certain operations and can beconfigured or arranged in a certain physical manner, in various exampleexamples, one or more computer systems (e.g., a standalone computersystem, a client computer system, or a server computer system) or one ormore hardware modules of a computer system (e.g., a processor or groupof processors) is configured by software (e.g., an application orapplication portion) as a hardware module that operates to performcertain operations as described herein.

In some examples, a hardware module is implemented mechanically,electronically, or any suitable combination thereof. For example, ahardware module can include dedicated circuitry or logic that ispermanently configured to perform certain operations. For example, ahardware module can be a special-purpose processor, such as aField-Programmable Gate Array (FPGA) or an Application-Specificintegrated Circuit (ASIC). A hardware module may also includeprogrammable logic or circuitry that is temporarily configured bysoftware to perform certain operations. For example, a hardware modulecan include software encompassed within a general-purpose processor orother programmable processor. It will be appreciated that the decisionto implement a hardware module mechanically, in dedicated andpermanently configured circuitry, or in temporarily configured circuitry(e.g., configured by software) can be driven by cost and timeconsiderations.

Accordingly, the phrase “hardware module” should be understood toencompass a tangible entity, be that an entity that is physicallyconstructed, permanently configured (e.g., hardwired), or temporarilyconfigured (e.g., programmed) to operate in a certain manner or toperform certain operations described herein. As used herein,“hardware-implemented module” refers to a hardware module. Consideringexamples in which hardware modules are temporarily configured (e.g.,programmed), each of the hardware modules need not be configured orinstantiated at any one instance in time. For example, where a hardwaremodule comprises a general-purpose processor configured by software tobecome a special-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware modules) at different times. Software canaccordingly configure a particular processor or processors, for example,to constitute a particular hardware module at one instance of time andto constitute a different hardware module at a different instance oftime,

Hardware modules can provide information to, and receive informationfrom, other hardware modules. Accordingly, the described hardwaremodules can be regarded as being communicatively coupled. Where multiplehardware modules exist contemporaneously, communications can be achievedthrough signal transmission (e.g., over appropriate circuits and buses)between or among two or more of the hardware modules. In examples inwhich multiple hardware modules are configured or instantiated atdifferent times, communications between or among such hardware modulesmay be achieved, for example, through the storage and retrieval ofinformation in memory structures to which the multiple hardware moduleshave access. For example, one hardware module performs an operation andstores the output of that operation in a memory device to which it iscommunicatively coupled. A further hardware module can then, at a latertime, access the memory device to retrieve and process the storedoutput. Hardware modules can also initiate communications with input oroutput devices, and can operate on a resource (e.g., a collection ofinformation).

The various operations of example methods described herein can beperformed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors constitute processor-implemented modulesthat operate to perform one or more operations or functions describedherein. As used herein, “processor-implemented module” refers to ahardware module implemented using one or more processors.

Similarly, the methods described herein can be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method can be performed by one or more processors orprocessor-implemented modules. Moreover, the one or more processors mayalso operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an API).

The performance of certain of the operations may be distributed amongthe processors, not only residing within a single machine, but deployedacross a number of machines. In some example examples, the processors orprocessor-implemented modules are located in a single geographiclocation (e.g., within a home environment, an office environment, or aserver farm). In other example examples, the processors orprocessor-implemented modules are distributed across a number ofgeographic locations.
